Understanding Child and Spousal Support in Ontario

Child Support

In Ontario, child support is calculated based on the non-custodial parent's income. The standard formula is 17.5% of the parent's net income, divided by 12 for monthly payments.

Spousal Support

Spousal support in Ontario is calculated differently for married couples and common-law partners. Married couples typically receive 25% of the payor's net income, while common-law partners receive 15%.

Example Calculation

If a parent earns $60,000 per year:

Monthly child support: $875
Monthly spousal support (married): $1,250
Monthly spousal support (common-law): $750

Modifications to Support

Courts may adjust support amounts based on factors like:

Special needs of the child
Educational expenses
Health care costs
Extracurricular activities
Special needs of the parent receiving support
